GEORGE HOGG, OF NEWBURG, NEW YORK.

MACHINE FOR WINDING SEWING-MACHINE BOBBINS.

SPECIFICATION forming part of Letters Patent No. 392,336, dated November 6, 1888.

' Application filed January 13,1888- Serial No. 260,589. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE Hose, of Newburg, in thecounty of Orange and State of New York, have invented a new and Improved Machine for Winding Sewing-Machine Bobbins, of which the following is a full, clear, and exact description.

My invention relates to a machine for winding thread upon sewing-machine bobbins; and

it consists in the construction, arrangement,

' and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional plan view of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged sectional elevation of the spindle-frame, and Fig. 4 is a detached perspective view of the lever for turning the bobbin-frame.

A represents the base of the machine, from which rise the two uprights B B, in which the which acts between the flange a and the edge of the adjacent upright B, so that the shaft is constantly pressed outward by the spring. Secured upon the shaft 0 between the uprights B B are the two pulleys E E. The pulley E is made fast to the shaft, while the pulley E is loose thereon, and this pulley is of some- What less diameter than the pulley E. The bosses f f of the pulleys E E are correspondingly beveled, as shown in Fig. 2, so that the difference in speed between the said pulleys will cause said beveled bosses running together to impart to the shaft 0 a slight longitudinal movement for laying the thread back and forth in the bobbin F being filled.

G represents the frame, to which a series of bobbins F to be filled are secured. This frame is journaled upon the stud or post H, which rises from the base A, the said post being shouldered at b, as shown in Fig. 3, to form a support for the frame. In the edge of the frame G are formed the recesses d, at the bottom of which are formed the screw-threaded recesses d, in which are screwed the spindles g, for holding the bobbins F. These spindles are split to form spring members, so that when the bobbins are forced upon their outer ends the spring action of the said members will retain the bobbins without other fastenings. The recesses d are made somewhat larger in diameter than the spindles g and recesses d, as shown clearly in Fig. 3.

The lower edge of the frame G is notched, as shown at h, to receive the projection j of the sleeve J, for turning the frame intermittently for bringing the bobbins F successively into line with the shaft 0 to be filled. The said sleeve is formed with a lever, J, and said sleeve fits upon the post H, and it is held up in contact with the notches h by the coiled spring J and said sleeve is notched or cut away at one side to form stop-shouldersm m, which act in contact with the fixed stud L to limit the back-and-forth movement of the lever J, also to cause the frame G to be carried just the proper distance with each forward movement of the lever.

The frame Gis kept from turning back with the backward movement of the lever J by the coiled spring M,placed upon the rod N,screwed into the post to hold the frame G in place. This spring acts through the plate G, attached to the rod N by a screw entering a slot, so that the said plate is free to move up and down, but not to rotate upon the said bolt. Between the plate G and the upper surface of the frame G is placed a'washer, G, of leather or other suitable material, so that slight pressure of the spring will cause the plate G to act as a sufficient brake to the frame G and prevent backward movement with the lever J.

In operation a bobbin is placed upon each spindle g, and the thread from the guide 0 c is attached to the bobbin and the shaft 0 revolved, which winds the thread upon the bobbin, as will be understood from Fig. 1. The

shaft 0 is slowly reciprocated by the diagonal faces ff, as above described, One bobbin being filled, the thread is broken and the lever J reciprocated to bring another bobbin into position, when the operation is repeated. The lever J will then be reciproeated to bring another bobbin into line, which in like manner will be filled, and so on indefinitely the filled bobbins being removed and empty ones supplied as the work proceeds.

Having thus described niyinvention, \vhatI claim as new, and desire to secure by Letters Patent, is-- 1. The shaft 0, having the thread-guide C and at one end, in combination with the spri ng D and the two pulleys E E, one loose the other fixed to the shaft and of different diameters and provided with beveled bosses f f, substantially as and for the purposes set forth.

2. The shaft 0 and threadguide U, in com bination with the frame G, sleeve J, and lever J, the frame being notched to receive a pro- 2c jection of the sleeve, substantially as and for in the base, substantially as described.
